MOTOR-WHEEL Specification of Iletters Patent.

Patented Jan. 25, 1921.

Application filed April 26, 1320.' Serial No. 376,471.

To all wlw/m. it may concern Be it known that I, MAURICE SAMUEL LOGAN, a citizen of Canada, residing at Loreburn, in the Province of Saskatchewan and Dominion of Canada, have invented a new and useful Motor-Vheel, of which the following is a specification.

My invention relates to mechanical improvements in motor wheel construction, the objects oi' which are, first, to improve the motor wheel mechanically; second, to give it the added eliciency of brake control.

I attain these objects by the mechanism illustrated in the accompanying drawing, showing a horizontal cross section through the center, in which a is the flywheel, b the drive shaft, c the crank, and e the drive pinion which engages the gears f. The motor wheel is propelled by the travel of said gears ,f f around the central gear g which is held stationary by the brake wheel 7L. Releasing the brake band z' i allows said gear r/ to rotate backward, so thatV no motion is imparted to the motor wheel. One end of said brake band is attached to the arm j and theother end to the horizontal arm of the angle lever 7c which is operated by the control rod Z attached to the other arm. The pinion m drives the cam shaft and magneto (not shown). x e are inwardly projecting hubs on which the motor wheel turns on ball bearings.

The distinctive features olf this motor wheel are: 1st, perfect balance-2nd, double durability, ,by reason ot' the double gear drive-3rd, balanced drive (lessenimgg'fricw tion on drive shaft bearings)-1lth, central drive-5th, more ily -wheel power-6th, brake control.

Aside from its use as a detachable push wheel, it may also be used, lst, as the drive wheel in a pedalless motor bicycle (seat lowered to within easy reach of the ground with both feet)-2nd, as the third wheel in a three wheel design-3rd, two together as the drive wheels in a 'four wheel design. These designs would be impossible except for the brake control, which allows the motor to run idle without the wheel being lifted oli' the ground.

l claim:

l. A rotatably mounted gear casing provided with a road wheel rim and carrying planetary gearing, in combination with a drive pinion and a brake controlled spur gear concentric with each other and with said gear casing, and operatively meshing with said planetary gearing, substantially as shown and described.

2. The combina-tion in a motor wheel, of a crank case with a hub attached rigidly thereto, a brake controlled element with a hub attached rigidly thereto, a road wheel mounted rotatably on said hubs, a drive shaft passing axially through said hubs, a drive pinion mounted rigidly on said shaft and between said hubs, a brake controlled spur gear concentric with said drive pinion, and planetary gearing carried by said road wheel and operatively connecting said drive pinion with said brake controlled spur gear, substantially as shown and described.

3. The combination in a motor wheel, of a rigid member provided with a hub m, a brake controlled member provided with a hub e, a gear casing mounted rotatably on said hubs and provided with a road wheel rim, a drive shaft passing axially through said hubs, a drive pinion mounted rigidly on said shaft and between said hubs, a spur gear attached rigidly to said brake controlled member and concentric with said drive pinion, and planetary gearing carried `by said gear casing and operatively connecting said drive pinion with said concentric spur gear, substantially as shown and described.

it, The combination in a motor wheel, of the rigid member fw, the hub a: attached to said rigid member, the brake controlled member h, the hub attached to said brake con trolled member, the road wheel p mounted rotatably on said hubs, the gear casing a attached to saidv road wheel and concentric therewith, the drive shaft 7) passing axially through said hubs, the drive pinion c mounted rigidly on said shaft and between said hubs, the brake controlled spur gear g mounted rigidly on said hub e and concentric with said drive pinion, the planetary gearing f carried by said road wheel and operatively connecting said drive pinion with said brake controlled spur gear, the fly wheel a attached rigidly to said drive shaft, the arm y' attached to said rigid mem- 'gle lever, all substantially as shown and de- Y ber and extending around the rim of said scribed.
